Description
The BTS 33 is a biological composting toilet that uses the process of aerobic decomposition to transform human
waste and toilet paper to a hygienically safe product (humus) that may be safely utilized if disposed of in a manner
described in this manual or by your local health authorities.
The BTS 33 does not have a heat source to aid in the evaporation process. Therefore, a drain tube MUST be installed
to evacuate any excess liquid. This liquid should be disposed of in a manner described in this manual or by your local
health authorities.
